A word remains to be said as to fortunes of Burnside's and Warren's forces, which were on the Federal right. Generals Potter and Willcox of the Ninth Corps made a quick capture of Early's advanced rifle-pits and were waiting for the order to advance on his main entrenchments, when the order of suspension arrived. Early fell upon him later in the day but was repulsed. Warren, on the left of Burnside, drove Rodes' division back and repulsed Gordon's brigade, which had attacked him. The commander of the Fifth Corps reported that his line was too extended for further operations and Birney's division was sent from the Second Corps to his left. But by the time this got into position the battle of Cold Harbor was practically over. The losses to the Federal army in this battle and the engagements which preceded it were over seventeen thousand, while the Confederate loss did not exceed one-fifth of that number. Grant had failed in his plan to destroy Lee north of the James River, and saw that he must now cross it. Thirty days had passed in the campaign since the Wilderness and the grand total in losses to Grant's army in killed, wounded, and missing was 54,929. The losses in Lee's army were never accurately given, but they were very much less in proportion to the numerical strength of the two armies. If Grant had inflicted punishment upon his foe equal to that suffered by the Federal forces, Lee's army would have been practically annihilated. The Federal general-in-chief had decided to secure Petersburg and confront Lee once more. General Gillmore was sent by Butler, with cavalry and infantry, on June 10th to make the capture, but was unsuccessful. Thereupon General Smith and the Eighteenth Corps were despatched to White House Landing to go forward by water and reach Petersburg before Lee had time to reënforce it.

Thus was completed the passage to the south of the stream of the two wings of the Army of the Potomac. But when the center under Burnside was driven back and severely handled at Ox Ford, Grant immediately detached a brigade each from Hancock and Warren to attack the apex of Lee's wedge on the south bank of the river, but the position was too strong to justify the attempt. Then it dawned upon the Federal general-in-chief that Lee had cleaved the Army of the Potomac into two separated bodies. To reënforce either wing would require two crossings of the river, while Lee could quickly march troops from one side to the other within his impregnable wedge. As Grant put it in his report, "To make a direct attack from either wing would cause a slaughter of our men that even success would not justify."
